v SAFETY ATTACHMENT FOR CAR-STOVES.

SPECIFICATION forming part of Letters Patent No. 371,350, dated October11, 1887.

Application filed March 18, 1837. Serial No. 231,406.

To ctZZ whom it may concern.-

Be it known that I, GEORGE A. OGLE, of Baltimore, in the State ofMaryland, have invented a new and Improved Safety Attachment forCar-Stoves, of which the following is a full, clear, and exactdescription.

This invention relates to fire-extinguishing attachments for car stoves,the parts being so arranged that when subjected to a powerful shockorjar the ball or weight will be dislodged and will fall upon areceptacle containing chemicals, which,when freed,will flow to the tire,there to generate ammoniacal vapor or carbonic acid gas, wherebythe thewill be immediately extinguished.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure l is a central sectional elevation of my improvedfire-extinguishing attachment for car-stoves, a portion of thestove-body being shown in section. Fig. 2 is a sectional plan viewtaken'on line :0 0c of Fig. 1, and Fig.

3 is a detail view illustrating the construction of the flanges of thetelescopically-connected tubes constituting a portion of the attachment.

In the drawings,'10 represents a stove-body, of which the fire-pot isshown at 11, the grate at 12, and the ash-pit at 13. Two or moreoutwardly-extending tubes, 14, are connected with the stove-body,preferably upon opposite sides thereof, the tubes being arranged forcommunication with the fire-pot of the stove by way of fines 2, asclearly shown.

The tubes 14 are each provided with telescopically-united sections 15and 16, the interlocking flanges of the sections 15 and 16 being shownat 3 and 4 and arranged so that by giving the section 16 a quarter-turnit may be removed from the section 15, but so that the two sections willbe held together when their flanges are thrown into register.

Vertical tubes 17 extend upward from the tubes 14, the bores of thetubes 17 and 14 communicating, and at a point near the upper end of eachof the tubes 17 there is formed a socket, 18, adapted to receive andhold a heavy metallic ball, 19, the sockets being so (No model.)

proportioned that the balls will not fall therefrom except when the caris subjected to a heavy jar. The upper ends of the tubes 17 are coveredwith perforated caps 20, which serve to ventilate the tubes 14,additional ventilation of said tubes being provided for through themedium of short tubes 21, which lead upward therefrom, said tubes 21being provided with perforated caps 22, as illustrated.

Within the tubes 14 there are placed receptacles 30, which contain thechemicals by which the ammoniacal vapor or carbonic-acid gas isproduced, the receptacles being preferably made of any fragilematerial-such as glass-which will be broken by the fall of the balls 19or by the collapsing of the telescopic sections 15 and 16 when saidsections are subjected to a strain such as that resulting from thetelescoping of the car. In order that the receptacles 30 may beprotected from the heat, and at the same time from any excessiverattling, I line the tubes 14 with asbestus packing, as shown at 6.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. The combination, with a stove, of tubesarranged in connection therewith and adapted to IBCtiVB chemical-holdingflasks and communicating with the fire-pot thereof, upwardly extendingtubes leading from the firstnamed tubes, and weights held in socketsformed at the upper portion of said tubes, substantially as described.

2. The combination, with a stove, of pipes 14, havingtelescopically-connccted sections 15 and 16, tubes 17, extending upwardfrom the pipes 14, connecting with the fire-pot of the stove, the tubes17 being provided with sockets 1S, and weights held by the sockets,substantially as described.

3. The combination, with a stove, of tubes 14, provided withventilating-tubes 21 and arranged to communicate with the fire-pot of 5ICC 4:. The combination, with a stove, of tubes arranged to communicatewith its fire-pot, ventilating-fines arranged in connection with saidtubes, an asbestus packing or lining fixed 5 within the tubes,chemical-receptacles carried by the tubes, and weights for crushing saidreceptacles when the stove is subjected to any undue shock or jar,substantially as described.
